MOTOR-CYCLE FRAME.

To all whom it may concern:

Be it known that I, Am HOLLIE HARMAN, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Motor-Cycle Frame, of which the followingis a specification.

My invention relates to a new and useful mot-or cycle frame and consistsof a tank for gasolene or fluids forming a continuous upper bar withoutany joint therein and in a novel means of mounting the head stemtherein.

It further consists in novel means for mounting the seat with respect tothe fluid tank.

It further consists of novel means for mounting the cylinder oil tank.

It further consists of novel means for supporting the engine directlyfrom the fluid tank.

It further consists of other novel features of construction, all as willbe hereinafter fully set forth.

Figure 1 represents a side elevation of a motor cycle embodying myinvention. Fig. 2 re resents a vertical sectional view of the flui tankand parts connected therein with the head stem omitted. Fig. 3represents a sectional view of a portion of the device showing themanner of connecting the supports or braces for the engine with thefluid or gas tank. Fig. 4 represents a vertical sectional view showingthe manner of supporting the battery casing and the tool casing.

In motor cycles now in use, owing to the arrangement and construction ofthe parts, the frame is extremely heavy and cumbersome and my inventionis designed to form a strong and durable construction and one that issimple and inexpensive to construct.

In the drawings, I have shown a form for carrying out my invention butit will be evident that the parts may be varied and otherinstrumentalities may be employed 1 which will come within the scope ofmy 1nvention and I do not therefore desire to be limited in everyinstance to the exact construction herein shown and described but desireto make such changes as may come within the scope of the invention andas may be necessary.

Similar numerals of reference indicate corresponding parts in thefigures.

heferring to the drawings, 1 designates a gasolene or fluid tank whichforms a continuous upper bar for the frame of the ma- Specification ofLetters Patent.

chine without any joints, said tank having suitable means for fillingthe same, in the present instance, through the opening 2 which is closedby the stopper 3. Brazed or otherwise secured in the forward end of thetank 1 is a tube or head 4 which is suitably inclined and with whichinclination the front wall 5 of the tank corresponds. Said tube or headis provided at its upper and lower ends with ball races 6 and said tubeis adapted to receive the head stem 7 of the fork 8 of the cycle, whichis adapted to be connected with the front wheel 9, said head stem 7having the ball races 10 thereon between which and the ball races 6 inthe head 4: the balls are retained, it being understood that said head 7is adapted to receive a handle bar pin 11 so that the guiding of themotor can be accomplished, the handle bars 12 extending rearwardly asdesired and being adjustable in any well known or desired manner.

13 designates a cylinder oil tank which is A connected with the fluid orgasolene tank 1 adjacent the lower wall thereof extending a suitabledistance therewith, said cylinder oil tank being secured to the fluidtank in any desired manner, in the present instance, by means of thebolt 14 and nuts 15, passing through a tube 16 which is brazed orotherwise secured to the gasolene or fluid tank, said oil tank 13 havinga tube 17 brazed thereto and in which is adapted to be seated a tube 18which is brazed or otherwise secured to the gasolene or fluid tank 1.Passing through said tube 18 is a bolt 19 having a nut 20 thereon, whichbolt is adapted to be connected with the cylinder 21 of the engine, saidcylinder also carrying the crank casing 22, in which the crank and itsoperative arts are mounted. By this means it will e seen that thecylinder and engine will have a direct vertical support and that thesame will be situated at a point adjacent the cylinder oil tank, so thatthe oil therein will always be kept warm or in proper consistency toproperly operate, the advantages of which will be evident. Connectedwith the cylinder oil tank 13 is a pipe 23 having a suitable valvetherein for conducting oil to the crank casing.

24 designates a carburetor which has suitable pi e connecting with theinterior of the gaso ene or fluid tank and also a pipe leading over tothe cylinder 21 of the engine.

25 designates a tube or pipe brazed to the fluid or gasolene tank 1through which Ali the engine.

shown the crank sprocket 39 as having a passes bolt 26 which serves tosupport the a continuous jointless upper bar forming a casing 27, whichis adapted to contain batteries 29, shown in dotted lines Fig. l, andthe induction coil 28 also shown in dotted lines, it being understoodthat any number of batteries may be employed, but I have shown in thedrawings only two. The casing 27 is preferably subdivided by a partition30 which forms a chamber 31 which is adapted to receive tools, etc.

32 designates braces or supports which extend from both sides of thecylinder casing and serve as additional supports for the engine saidsupports or braces, it being noted, being also secured to the gasoleneor fluid tank 1 which thus serves as the main support for the operativeparts of the motor cycle. In the present instance, I have shown a tube33 brazed to the said tank 1 1 and it has a bolt 34 passing therethroughwhich also passes through suitable openings in the supports 32 and bymeans of a nut 35 the parts are firmly held in position. A suitable formof belt 36 passes around a pulley 37 carried by the rear wheel 38 inorder to drive the mechanism while any form of means operated by therider can be employed for driving the cycle and for turning the hindwheels in order to start In the present instance, I have chain 40passing around the same, said chain also passing around a sprocket onthe rear wheel. Cranks ll serve to operate the said. crank sprockets.

42 designates a seat which is suitably mounted upon the rod 43, said rodbeing likewise secured to the gasolene or fluid tank 1 and is preferablyso secured as to lie in the same horizontal plane with said tank, aswill be evident from Fig. 1. In the present instance the seat isconnected with the tank 1 by having the boss 44: connected with saidtank, the inner bore of i: which is threaded and tapered and in which wI have formed a strong, light and durable construction and that my fluidtank 1 serves as a continuous upper bar for the frame without anyjoints, that the cylinder oil tank is connected with said gasolene tankrunning substantially parallel therewith and is situated, as beforestated, adjacent the engine for keeping the oil within the tank inproper condition. I am also enabled to form a strong and neatconstruction for the reception of the head stem of motor cycle by themeans described.
